Pros & Cons of different Central Heating Systems

[km2000]

I am intending replacing central heating system soon for various reasons, and have searched long and hard both here and elsewhere for the relative pros and cons of conventional versus combi systems as well as seeking advice from a number of plumbers.

Thing is ... nowhere seems to detail an exhaustive list of what the relative pros and cons are (except that oilman likes combis as it keeps plumbers in work!). I have heard umpteen different opinions on this site and others about what is best for various different scenarios.

So.. here is the challenge ... WITHOUT me revealing my requirements (space, cost, efficiency, usage etc) can anybody propose at least a rough guide on how to choose.

Seems like this topic is raised very regulary and would benefit all if this was documented once and for all.

Do a search for "combi disadvantages". Should give you something to go on.

No a system is designed by a competent heating installer on these requirements. The only installer who would guide your choice with no information on your requirements is one I certainly wouldn't want in my house!
